Physics Lab 1 Skills Test Notes

This set of flashcards covers key concepts from a physics lab regarding measurement techniques, units, and density.

Vernier Caliper

An instrument used to measure small dimensions accurately and precisely.

Density

The mass per unit volume of a substance, often used to identify materials.

Percent Difference

A measure that shows how close an experimental value is to a handbook value; a smaller difference indicates greater accuracy.

SI Units

The International System of Units used for measurements, including meters for length, kilograms for mass, and seconds for time.

Volume

A measure of how much three-dimensional space an object occupies, calculated as length cubed.

Aluminum Density

Approximately 2700 kg/m³; considered a low-density metal.

Copper Density

Approximately 8960 kg/m³; considered a high-density metal.

Conversion Rule

To simplify conversions, multiply by fractions that equal 1, allowing units to cancel.

Electronic Balance

An instrument used to measure mass with high precision.

How to calculate volume of a cylinder

Use the formula V = πr²h, where r is radius and h is height.
